Variable depth gullets provide more efficient chip clearance; 4/6 variable pitch teeth for reduced noise and improved performance. Electron beam weld for stronger, longer lasting teeth.
Reinforced to cut stronger, last longer and resists tooth strippage. High speed steel teeth resist breaking and offer extended life. Thick backing plate with holes for drive pins resists damage due to high torque.
Bi-metal construction with 8 percent cobalt for increased wear resistance. Optimized tooth form for faster cutting with wide, angled and offset slots for easy plug access. Plug Jack, an all access slot design for fast plug removal.
Double tooth for longer life and improved durability, cuts material faster for faster drilling. Thick, hardened backing plates prevent thread stripping. Increased high speed steel height improves hole saw durability.
Features Rip Guard, the strongest tooth form in the industry; Plug Jack, an all access slot design for fast plug removal; Bi-metal construction with 8% cobalt for increased wear resistance.
Ideal for drilling wood, plastic, aluminum, metal and stainless steel. 60mm (2-3/8") cutting depth for deeper holes in one pass and increased productivity. Snap-Lock mandrel system for a quick and easy change with no down time.
